four specimens are more slender in form than the three females from 
which the main description was taken. 
I have another 9 variety from New Jersey, which has the longitu¬ 
dinal lines of the thorax bright ferruginous; the spots on each side of 
the metathorax are triangular and become confluent on the disk, and 
the legs are almost entirely ferruginous; this specimen is more robust 
than the females above described. 
Also another 9 variety, probably of this species, from Pike’s Peak, 
which is ferruginous, with the sides of the face, the collar, tubercles, 
tegulge, a quadrate patch on the pleura, a large quadrate spot on the 
scutellum, a transverse line below it on the postscutellum, a small spot 
on each side of the metathorax near the insertion of the abdomen, part 
of the coxae and the usual fasciae on the abdomen, yellow; there is no 
appearance of longitudinal lines on the thorax, and the scutellum is 
flat, not subbilobate; the legs and antennae are entirely ferruginous. 
It may be a distinct species. In this specimen, the right wing has the 
third submarginal cell petiolated, as mentioned before on page 281.
